Re: Linux & BSD's lpr exploit

I tried to use the lpr exploit on my machine which runs Redhat 4.0.
It says "lpr: lp: unknown printer".  It is setuid.  I was wondering if you
could set lp so that the program would work.  You could do it by
enviroment variable, but what would you set it to if there isn't a printer
for the machine.  Is it just not possible for the bug to work on Redhat
4.0?  I would hate for one of my users to find a way to exploit it after i
thought it was safe.   My kernel version is 2.0.23, but I'm going to
upgrade it to 2.0.24 tonight.


Do I not need to worry about this bug?  any help is appreciated.
